densation product or a substance containing such a product. An escutcheon of that material is desirable in t-hat it is easily shaped and is pleasing in appearance, but a diliiculty inheres in its use where a knob is used. The spindle of a. door knob is ordinarily Y somewhat loosely supported and therefore is capable of a limited movement sidewise. It has been found that attempts to use a l molded escutcheon have been unsuccessful because vthe knob or its spindle in moving sidewise engages the molded material and breaks it.

In the accompanying sheetof drawings, in which Figures l and 2 are respectively an elevation and a central sectional view, I have shown an escutcheon of molded material which is entirely practicable and avoids the likelihood of the knobs causing a fracture in the molded material.

The escutcheon is made up principally of molded material. The molded face portion 10 is given any desired surface configuration in the molding operation and has a shallow recess 11 in its back, i. e. in the side adapted to rest against the door sash. A metal plate 12 rests in the recess and lies flush with the surface of the back. vThere is an annular boss 13 formed in the molded material at the rim of the opening 14 into which the shank of the knob extends and through which lthe knob spindle passes. In the re-enforcing plate 12, there is an opening 15 in register with the opening 14 in the molded material, 'but of smaller size.-

The escutcheon is held to the door by screws passing through the eyelets 16 which serve to hold the two parts 0f the escucheon together. A key hole 17 may be provided when desired and the idea of a smaller hole in the plate than in thev molded material may be applied to it as well if it is found that there is any tendency to break the molded material in manipulating the key. Ordinarily it is not necessary to do so.

Neither normal movement of the knob sidewise nor Vmovement coupled with considerable force, as when the door ysticks'and is lifted by lifting the knob, causes fracture of the escutcheon` since the opening in the molded material is large enough so that with the maximum amountof play of the spindle, the part of the ,knob unit adjacent the molded material will not press against it.

I claimc i i 1. An escutcheon kcomprising a portion of molded material and a re-enforcing member, the two having registering openings, the opening inthe re-enforcing member being the smaller, forthe purpose described.

l2. An escutcheoncomprising a face p0rtion of molded materiall having an opening for a knob spindle, and a re-enforcing plate eoV on the back thereof, said plate having an opening in register with and smaller than the opening in the face portion, for the purpose described. c

3. An escutcheon comprising a face portion of molded material having an opening therethrough for a knob spindle, andra shallow recess in its back, together with a reenforcing plate resting in said recess, said plate having an opening in register with and smaller than the opening in the molded material, for the purpose described.

4. An escutcheon comprising a face portion of molded material having an opening' .therethrough and an annular boss at the rim Y ofthe hole, togetherV with a re-enforcing plate having aL smaller opening in register with the opening lin thek face portion, for the purpose described.

In testimony whereof I vhave signed my name to this specification.
